Marquis Daniels removed on a stretcher

Marquis Daniels fell to the ground after a collision with Gilbert Arenas and laid motionless on the Garden floor for about five minutes.  

He got the ball on the right side of the floor and turned to drive on Gilbert Arenas when he hit the side of his head and went straight down.  Paramedics stabilized him and removed him on a stretcher.  The good news is he gave the crowd a thumbs up sign after he was on the stretcher, so whatever happened to him may have just been temporary. 

We'll update this post as more information becomes available.
